What Pixel Size Should I Use? A Guide to Block Resolution

Pixel size — also called block resolution or grid size — determines how many source pixels collapse into one output block. It's the single most impactful setting in any pixel art conversion, and choosing the wrong value is the most common reason pixel art looks "off."

The pixel size scale

Pixel size	Visual effect	Output resolution (from 1920×1080)	Best for
2-4 px	Barely pixelated, retains most detail	960×540 to 480×270	Subtle retro filter, large prints
4-8 px	Clearly stylized, features recognizable	480×270 to 240×135	Portraits, detailed photos
10-14 px	Balanced — iconic pixel art look	192×108 to 137×77	Most photos, avatars, social media
16-32 px	Chunky, 8-bit console aesthetic	120×68 to 60×34	Minecraft builds, game sprites, retro art
32-64 px	Very abstract, barely recognizable	60×34 to 30×17	Minimalist art, icons, abstract

Choosing by content type

Portraits and faces

Faces need enough resolution to preserve the eyes, nose, and mouth as distinct features. At 4-8 px, most faces remain clearly recognizable with visible expressions. At 10-14 px, the face becomes stylized but still identifiable. Below 16 px, individual features merge into blocky abstractions — which can be the desired effect for avatar silhouettes.

Landscapes and scenery

Landscapes tolerate much coarser grids because the eye reads them as shapes and color fields rather than fine details. A mountain range at 16-32 px still reads as mountains. A forest at 24 px still reads as trees. Use larger pixel sizes for scenery to get the most dramatic pixel-art effect.

Text and logos

Text requires high resolution to remain legible. Keep pixel size at 4-6 px for anything with readable text. Logos with simple geometric shapes can go to 8-12 px before losing recognizability.

Game sprites and characters

Classic game sprites use specific resolutions: NES sprites are 8×8 or 8×16 pixels, SNES sprites go up to 64×64. For a full-body character sprite from a photo, target 32-64 px to match these conventions.

The golden ratio of pixel art

There's a sweet spot where pixel art looks best: when the output resolution is roughly 1/10th to 1/20th of the source resolution. For a 1920×1080 photo, that's 96-192 pixels wide — corresponding to pixel sizes of 10-20 px. This range produces output that's clearly pixel art while retaining enough detail to be recognizable.
